Carboniferous palynology of the Loppa High Barents Sea, Norway
Nine palynological intervals, A-I in ascending order, are recognised in the Carboniferous succession of the well 7120/2-1 on the Loppa High in the western Barents Sea. Within the Billefjorden Group intervals A-E are correlated with the early Visean to Serpukhovian Pu to TK Miospore Zones of western...
